What you need to know about Image Files

Greetings from Digital Art Expressions, Las Vegas Nevada.

Designs are created so you can use them for any event!  They are created in Corel Draw X7. Then converted to Hi-res PNG format, then up-loaded @ 300pp. So if you want to reduce the image. No problem! 

NOTE: If you want your photo, design or one of my designs on a product from one of my stores  and you would like my help free of charge please contact me at daelasvegas@cox.net subject Requesting Help

 

The JPEG Format
The JPEG format, with its support for 16.7 million colors, is primarily intended for photographic images. The internal compression algorithm of the JPEG format, unlike the GIF format, actually throws out information. Depending on what settings you use, the thrown out data may or may not be visible to the eye. Once you lower the quality of an image, and save it, the extra data cannot be regained so be sure to save the original.

 

The GIF Format
GIF files support a maximum of 256 colors, which makes them practical for almost all graphics except photographs. The most common method of reducing the size of GIF files is to reduce the number of colors on the palette. It is important to note that GIF already uses the LZW compression scheme internally to make images as small as possible without losing any data.

 

The PNG format
The newest, file format that's widely supported by the Web is PNG (pronounced Ping). PNG was developed to surpass the limitations of GIFs, and as a means by which developers can avoid having to worry about the patent licenses associated with other formats. PNG was designed to offer the main features of the GIF format, including streaming and progressive file formats. It also provides greater depth of color, catering to images up to 24 bit in color.

What is a Vector Design?

All  designs are created in Vector format using Corel Draw.

Vector graphics are based on vectors (mathematical expressions, also called paths, or strokes) which lead through locations called control points. Each of these points has a definite position on the x and y axes of the work plan. Each point, as well, is a variety of database, including the location of the point in the work space and the direction of the vector (which is what defines the direction of the track). Each track can be assigned a color, a shape, a thickness and also a fill. This does not affect the size of the files in a substantial way because all information resides in the structure; it describes how the vector was drawn. (bitmap, JPG) graphics, or called Raster images are based on pixels and so when scaled there is a loss of clarity, while vector-based graphics can be scaled by any amount without degrading quality.
